The Department of Sustainability and Environment (DSE) will be conducting a high-priority controlled burn along the top of Mount Dandenong today.

The 30-hectare fire will be lit to reduce the bushfire risk to surrounding tourist accommodation, Melbourne's TV transmission towers and nearby satellite dishes.

Smoke and flames will be visible from the eastern suburbs and crews will remain on site throughout the night to patrol the fire.

Heaviest Snowfall Forecast

Recent spring warmth has come to a crashing halt for parts of the Rockies and Plains as Winter Storm Walda brings heavy snow, very high winds, and a drastic drop in temperatures that has even led to freakish sub-freezing severe thunderstorms.

We have a classic spring storm pivoting out of the West into the Plains.  This bullish dip in the jet stream is bringing not only a winter storm, but an outbreak of severe thunderstorms this week in the warmer air to its east - and in some cases, even over the colder air behind its cold front.

TROUBLE CONTACTING MARS: NASA is suspending communications with Mars rovers and orbiters this month as the Red Planet passes almost directly behind the sun. Mars is less than 2o from the sun now, and the distance will narrow to a mere 0.4o on April 17th. "The sun can easily disrupt radio transmissions during the near-alignment," explains a NASA press release.

 

FAST-GROWING SUNSPOT: Solar activity is low, but a fast-growing sunspot could break the spell of quiet. AR1718 has more than doubled in size during the past 48 hours as shown in this movie from the Solar Dynamics Observatory:

Parts of eastern Tasmania were flooded by persistent rain overnight, leading to flooding but this rain is now clearing, causing the flooding to ease.

A severe weather warning for heavy rain has now been cancelled.

The biggest falls were in the Lower Derwent to the east of Hobart, where some locations gained more than 100mm.

The heat wave is here to stay, at least for the current week. With mercury level showing a steady rise across the State, any immediate relief from the sweltering conditions is unlikely. The formation of a troughline around Friday may decide how the next fortnight will go.

On Monday, as many as 14 stations __ spread across coastal, western, northern and central Odisha pockets  __ recorded 40-degree-plus temperature signalling that the entire State was under the grip of  blistering conditions. Titlagarh (42.2 degree) and Sambalpur (42 degree) were the hottest places.
